Description

BACKGROUND
A tape library may include a plurality of tape drives which receive tape cartridges. The tape library may physically transfer the tape cartridges to the tape drives to read data from and write data to the tape media such as magnetic media of the tape cartridges.
BRIEF DESCRIPTION OF THE DRAWINGS
Non-limiting examples are described in the following description, read with reference to the figures attached hereto and do not limit the scope of the claims. Dimensions of components and features illustrated in the figures are chosen primarily for convenience and clarity of presentation and are not necessarily to scale. Referring to the attached figures:
FIG. 1 is a block diagram illustrating a tape library according to an example.
FIG. 2 is a schematic view illustrating the tape library of FIG. 1 according to an example.
FIG. 3 is a flow chart illustrating a method of upgrading firmware with upgrade information from a tape cartridge according to an example.
FIG. 4 is a block diagram illustrating a computing device such as a tape library including a processor and a non-transitory, computer-readable storage medium to store instructions to operate the tape library to upgrade firmware with upgrade information from a tape cartridge according to an example.
 DETAILED DESCRIPTION
A tape library may include a plurality of tape drives which receive tape cartridges. The tape library may physically transfer the tape cartridges to the tape drives to read data from and write data to the tape media such as magnetic media of the tape cartridges. Data may be read from and written to tape media of the tape drive using firmware of the tape drive. A tape cartridge manufacturer, however, may produce a new version of a tape cartridge including tape media having characteristics that may prevent the current firmware of the tape drive from reading data from and writing data to the new version of the tape cartridge. That is, the current firmware of the tape drive may be incompatible with the new version of the tape cartridge. Further, additional functionality may want to be provided to the tape library and/or tape drive. Accordingly, for the new version of the tape cartridge to work with the tape drive, the current firmware may have to be manually upgraded. Such manual upgrading may require time from a user and reduce throughput of the tape library.
In examples, a method of upgrading firmware with upgrade information from a tape cartridge may include, amongst other things, receiving a respective tape cartridge of a plurality of tape cartridges by a respective cartridge receiving compartment of a plurality of cartridge receiving compartments. The method may also include determining whether an external tape identifier obtained from the respective tape cartridge in a wireless manner corresponds with an internal tape identifier of one of the plurality of information modules by the tape drive manager. The affirmative identifier determination may be made in response to the respective cartridge receiving compartment receiving the respective tape cartridge. That is, in response to the respective cartridge receiving compartment receiving the respective tape cartridge, the tape drive manager may engage in determining whether the respective external and internal identifiers correspond with each other and, if so, an affirmative identifier determination is made. The method may also include upgrading the respective firmware of a respective information module associated with the respective tape cartridge by the tape drive manager. For example, the tape drive manager may use upgrade information obtained from the respective tape cartridge in the wireless manner based on the affirmative identifier determination. Accordingly, a tape cartridge may be received in a cartridge receiving compartment of a tape library to automatically and wirelessly upgrade current firmware thereof to enable the tape cartridge to be read from and written to. Thus, by automatically upgrading the tape drive upon an insertion of a respective tape cartridge therein, a previously incompatible tape cartridge may achieve compatibility with the tape drive and/or a compatible tape cartridge may provide additional functionality to the tape library and/or tape drive.
FIG. 1 is a block diagram illustrating a tape library according to an example. Referring to FIG. 1, in some examples, a tape library 100 may include a plurality of cartridge receiving compartments 10 and a tape drive manager 12. The plurality of cartridge receiving compartments 10 may receive a plurality of tape cartridges, respectively. The tape drive manager 12 may include a memory 14 to include a plurality of information modules 15 a and 15 b associated with the plurality of tape cartridges, respectively. Each information module 15 a and 15 b may include an internal tape identifier 16 a and 16 b to identify a corresponding tape cartridge and a firmware 17 a and 17 b to cause the tape drive manager 12 to write data to and read data from the corresponding tape cartridge.
Referring to FIG. 1, in some examples, the tape drive manager 12 may also determine whether an external tape identifier obtained from the respective tape cartridge in a wireless manner corresponds with an internal tape identifier 16 a and 16 b of one of the plurality of information modules 15 a and 15 b in response to a respective tape cartridge receiving compartment 10 receiving a respective tape cartridge. That is, in response to the respective cartridge receiving compartment 10 receiving the respective tape cartridge, the tape drive manager 12 may engage in determining whether the respective internal tape identifier 16 a and 16 b and the external tape identifier correspond with each other and, if so, an affirmative identifier determination is made.
For example, the respective internal tape identifier 16 a and 16 b and the external tape identifier may correspond with each other if they are the same. Additionally, the respective internal tape identifier 16 a and 16 b and the external tape identifier may correspond with each other if at least one of them is within a target group such as within an identifier range. In some examples, the internal tape identifier 260 n and 260 nn may be alphanumeric characters, barcodes, and the like. The tape drive manager 12 may also upgrade the respective firmware 17 a and 17 b of a respective information module 15 a and 15 b associated with the respective tape cartridge using upgrade information obtained from the respective tape cartridge in the wireless manner based on an affirmative identifier determination. Further, the tape drive manager 12 may also subsequently execute the upgraded firmware to write data to and read data from the respective tape cartridge. Thus, by automatically upgrading a respective tape drive upon its insertion therein, a previously incompatible tape cartridge may achieve compatibility with the tape drive and/or a compatible tape cartridge may provide additional functionality to the tape library 100 and/or tape drive.
FIG. 2 is a schematic view illustrating the tape library of FIG. 1 according to an example. Referring to FIG. 2, the tape library 200 may include a plurality of cartridge receiving compartments and a tape drive manager as previously disclosed with respect to FIG. 1. In some examples, the tape library 200 may also include a plurality of tape drives 280 a and 280 n, a tape library manager 285, a plurality of tape cartridges 290 a and 290 n, a wireless transfer device 275 a and 275 n, and a plurality of tape drive managers 220 and 220 n. For example, each one of the plurality of tape drives 280 a and 280 n may include a respective cartridge receiving compartment 282 a and 282 n. In some examples, the respective cartridge receiving compartment 282 a and 282 n may include a slot to receive the respective tape cartridge 290 a and 290 n and a sensor to detect receiving the respective tape cartridge 290 a and 290 n therein. For example, the sensor may be a mechanical and/or electrical sensor to detect the physical presence of the respective tape cartridge 290 a and 290 n. The tape library manager 285 may transfer the respective tape cartridge 290 a and 290 n to the respective cartridge receiving compartment 282 a and 282 n of a respective tape drive 280 a and 280 n to allow the tape drive manager 220 a and 220 n to write data to and read data from the respective tape cartridge 290 a and 290 n.
Referring to FIG. 2, in some examples, the respective tape cartridge 290 a and 290 n may include tape media 295 a and 295 n, an external tape identifier 292 a and 292 n, and upgrade information 293 a and 293 n.
